The highest priority router is chosen as the RP. If two or more routers have the same priority, a
hash function in the BSR mechanism is used to choose the RP, to make sure that all routers in the
PIM-domain have the same RP for the same group.
Use the ip pim rp-candidate IFNAME PRIORITY command to change the default priority of any
candidate RP.
At Router_D, the show ip pim sparse-mode rp-hash command shows that Router_C has been
chosen as the RP for a specified group.
PIM group-to-RP mappings
Use the show ip pim sparse-mode rp mapping command to display the group-to-RP mapping
details. The output displays information about RP candidates. There are two RP candidates for
the group range 224.0.0.0/4. RP Candidate 10.10.1.5 has a default priority of 192, whereas, RP
Candidate 172.16.1.2 has been configured to have a priority of 2. Since RP candidate 172.16.1.2
has a higher priority, it is selected as RP for the multicast group 224.0.0.0/24
